A/D Initialization
Preliminary
; Select Bank1
; Configure A/D inputs
; Enable A/D interrupts
; Select Bank0
; RC Clock, A/D is on, Channel 0 is selected
;
; Clear A/D interrupt flag bit
; Enable peripheral interrupts
; Enable all interrupts
; Start A/D Conversion
; The ADIF bit will be set and the GO/DONE
; bit is cleared upon completion of the
;
A/D Conversion.
